FUJIFILM continues its series of hands-on videos, guiding new and aspiring users of the company’s Cine camera through its menus and features. This video takes us deeper into the ETERNA 55 electro-optic options, be it with native FUJIFILM G-Mount lenses, PL optics, or other creatively adapted options. The video will walk you through the camera’s modern autofocus option as well as its rather comprehensive optical corrections capabilities.

The FUJIFILM ETERNA 55 is a rather unusual cinematic camera. Built around the tallest sensor in and around its price range, the camera offers quite an interesting perspective for cinema recording that usually adorned wider, almost panoramic sensors and formats. Such a sensor calls for a fresh look at optics as well, and FUJIFILM seems to equip the new ETERNA 55 with a full toolkit of electro-optical adjustments.

To learn everything about the details of the GFX ETERNA’s manual and autofocus settings, watch the video above! Below, we will discuss lensing options for the GFX ETERNA’s very large sensor.

Working with FUJIFILM G-Mount lenses

At its barebones form, the FUJIFILM GFX ETERNA 55 uses the company’s well-known G Mount. Over the years, FUJIFILM has developed more than 15 GF lenses, primarily designed for still photography, featuring fly-by-wire manual focus and a clear emphasis on high resolution. While these are perfectly usable for filmmaking, FUJIFILM has also launched the FUJIFILM GF 32-90mm T3.5 PZ OIS WR, a fully cinematic zoom lens, for various motion capture use cases. With these lenses, the ETERNA 55 uses an autofocus system derived from the well-known GFX100 II. Features such as face detection and subject recognition are included, capabilities that have become standard in post-hybrid-revolution cameras. All GF lenses also offer full sensor coverage, which is no small feat given the 33mm × 44mm sensor’s size.

Adapted PL or vintage lenses

While the FUJIFILM GFX ETERNA 55 offers various modern features, many will have its unique sensor and color science utilized with more traditional optics. For those of us who like cine lenses or vintage glass, the camera supports interchangeable mount adapters. A PL mount adapter is included as standard with the ETERNA 55, and third-party adapters can be used for mounts such as LPL or other legacy lens systems, as well as a slew of new entries into the field of cine optics from recent years.

But the combination of an unusually large sensor with lenses mostly made for smaller or shorter sensors can cause some coverage issues. Vignetting is the most common, but even with decent coverage, we’ll sometimes see enhanced distortion, reduced sharpness, etc., when pushing the envelope to such extents. FUJIFILM has devised a solution: A dedicated Mount Adapter Setting within the Recording menu. This allows for up to six configurations to be stored, each assigned a custom name and focal length. These profiles go way beyond simple labeling, offering in-camera image-correction tools that compensate for optical imperfections commonly found in third-party lenses.

In-camera correction tools for adapted glass

Three key correction options are available when using adapted lenses:

• Distortion Correction allows adjustment for barrel or pincushion distortion using weak, medium, or strong presets. Calibration is performed visually, typically by referencing a grid pattern. While it cannot correct extreme distortion, it can compensate for subtle lens behavior.
• Color Shading Correction enables per-corner color offset adjustments. This is particularly useful when working with older lenses that may exhibit coating degradation or uneven color rendering across the frame.
• Peripheral Illumination Correction addresses light falloff in the corners. It cannot compensate for lenses that can’t fully cover the sensor, resulting in hard vignetting, but it may help keep vignettes under control, creating a cleaner perception.

Unique tools for a unique camera

The FUJIFILM GFX ETERNA 55 is a unique camera. It uses a sensor specifically designed for stills in a body designed for cine, merging together a unique blend of capabilities. Special blends of features aren’t quite rare in the hybrid age, but each one is special in its own right. The integration of these tools demonstrates that FUJIFILM anticipates users combining the GFX ETERNA 55 with a wide range of optics, from modern cinema zooms to retro vintage lenses – a truly versatile system.

The Cine question

As shown in our recent review of the GFX ETERNA 55 (and in various other reviews and articles), the term “Cine” is not as consistent as it was. FUJIFILM took a significant leap (of faith?) with its first full-on cine camera, and left some things to be desired, as well as several workarounds users may have to use. However, the company, known for its Kaizen philosophy, didn’t leave users to wonder and crafted some innovative solutions, tools, and features to make the most of this unorthodox camera. It’s this kind of philosophy that brings new users and preserves old ones.

Will you opt for the no-fuss GF lenses on your FUJIFILM GFX ETERNA 55, or will you dive into the crazy world of vintage optics? Will such tools make your decision easier? Let us know in the comments.
